How Can Exposure Levels be Controlled in Studies?

Researchers can use various strategies to control for exposure levels in epidemiological studies:
Stratification: Dividing participants into subgroups based on exposure levels to analyze each group separately.
Matching: Pairing participants with similar characteristics to reduce confounding variables.
Randomization: Randomly assigning participants to different exposure levels to minimize biases.
Standardization: Using consistent methods and tools to measure exposure across all participants.
